报告题目：Efficient surface tension force model and adaptive mesh refinement solver for simulating multiphase flows

报告摘要：In this talk, a free energy-based continuum surface tension force (FE-CSF) model is applied to calculate the surface tension force. Since the new model has a clear physical basis and does not need to introduce a regularization function, it suffers less from numerical diffusion and performs better in mass conservation, numerical stability and accuracy. Furthermore, in order to simulate complex multiphase flows with high computational efficiency and accuracy, an adaptive mesh refinement-multiphase lattice Boltzmann flux solver is developed. In the method, the multiphase lattice Boltzmann flux solver (MLBFS) is used to solve the flow field and the level set method is adopted to capture the interface.
